Abstract: 1,209,935. Measuring properties of moving sheets; radiation gauges. INDUSTRIAL NUCLEONICS CORP. Nov.6, 1967 [Nov. 8, 1966], No.50389/67. Headings G1A and G1N. The average value of a property (e.g. weight per unit area, thickness, or moisture content) of a sheet material (e.g. paper) being wound up into a roll is measured by traversing a gauge 20 back and forth across the width of the moving sheet and averaging the output signals from the gauge over the time interval between the start and the end of the roll. As shown in Fig. 1, the average computer 30 is reset and started in response to a signal from a unit 58 for initiating a new roll. The end of the roll is sensed by a limit switch 68. In Fig. 3 (not shown) a manually selectable width signal and a footage counter are provided and the total area and weight of the roll are calculated. The computer may also calculate the standard deviation of the measured property. The gauge may be a radiation gauge for measuring weight per unit area, a magnetic gauge for measuring thickness, or a capacitive gauge for measuring moisture content.

Abstract: 1,241,304. Compander. WESTERN ELECTRIC CO. Inc. 24 Oct., 1968 [26 Oct., 1967], No. 50515/68. Heading H4R. A two-way circuit which can function as a compander, compressing outgoing signals and expanding incoming signals, comprises a summing amplifier 22 to which the incoming signal and the outgoing signal are applied and the output from which is added, in phase opposition, to the incoming and outgoing signals via attenuators n1 and n2 respectively. By suitable choice of the attenuation ratios of attenuators n1, n2, m1 and m2, the circuit can provide an impedance match to both lines 10, and 32. In addition by making attenuators m1 and n2 non- linear, e.g. as shown in Fig. 4B, the arrangement is given compander characteristics such that the signal from line 10 is compressed before transmission to line 32, and the signal from line 32 expanded before transmission to line 10. In an alternative embodiment the signals from the lines are applied to the attenuators m1 and m2 via emitter followers while the sum signals are applied to the lines from attenuators n1 nad n2 via separate common emitter amplifying stages with undecoupled emitter resistors.
